Perceptual latency of sensory stimuli is changed with motor-auditory but not with motor-visual temporal recalibration

Abstract (in Japanese) (See Japanese page) 
(in English) Perception of synchrony between one's own action and its sensory feedback can be recalibrated after exposure to an induced delay (temporal recalibration: TR). TR might be obtained by a motor shift (change in motor execution timing) and/or a sensory shift (change in peceptual latency). We examined whether perceptual latency changes with a shift of subjective synchrony. Participants were exposed to a delayed visual or auditory feedback after voluntary action, and then did a synchronous tapping (ST) task (to measure subjective synchrony) and a simple reaction time (SRT) task (to measure latency shifts). For auditory stimuli, SRT became significantly shorter by 6.5 ms after exposure to motor-auditory (MA) delays. This auditory speed-up was accompanied by 33.4 ms shift of the point of subjective simultaneity (PSS) in the MA-ST task. Exposure to visually-delayed stimuli did not change visual SRT (< 0.1 ms), though the MV tap-asynchrony was significantly shifted by 16.3 ms. These results suggest that the MA-TR is more potent than MV-TR and that shifts in perceptual latency can partly account for adaptation to temporal delays.
